How to Automatically Export Bookmarks To HTML File in Firefox

It is possible to configure Mozilla Firefox to automatically export bookmarks to an HTML file. This can be enabled with a hidden option in about:config. When enabled, the browser will automatically export your bookmarks to an HTML file and save it under your Firefox profile, typically stored under C:\Users\Your User Name\AppData\Roaming\Mozilla\Firefox\Profiles\<profile_name>.default\bookmarks.

If you have a bunch of bookmarks in the Mozilla Firefox browser, you might be interested in exporting them to an HTML file. This is extremely useful because you can have a backup of your bookmarks. Also, you can open that file later on some other PC or mobile device where Firefox is not installed. You can also import the HTML file in another browser on the same PC or another device.

Since 2017, Firefox has the Quantum engine which comes with a refined user interface, codenamed "Photon". The browser doesn't include support for XUL-based add-ons any more, so all of the classic add-ons are deprecated and incompatible. See
